I want to be able to store website configuration without the use of mysql. I also want the user to be able to change this information from a web page. What's the best methods to do so?
Valuable options are a SQLite database, or just a PHP file containing a serialized array if you want a really simple option:
// reading configuration
$config = unserialize(file_get_contents('config'));
// storing configuration
file_put_contents('config', serialize($config));
